Distribution Function of Random Vortex Velocities in the Turbulent Ionospheric Current

A theoretical expression for the distribution function of random vortex velocities in the turbulent ionospheric current has been derived. The validity of the theory has been tested by: 1) a correlation between theoretical velocity variations and results of computer simulation of the GD instability; 2) a comparison between theoretical and experimental shapes of Doppler spectra.

Lithosphere geodynamics research by satellite measurements of electromagnetic emission

The variations of the low-frequency (0.1-20 kHz) emission intensity, the density of the low-energetic electron flux and the plasma temperature measured on the "Intercosmos 19" satellite above the deep faults of the Norwegian Sea, Baltic Shield, Barents and Kara Seas and West Siberian Lowland have been considered. These regions represent a consecutive change of the Earth crust structure and its geodynamic mode in the zone of the transition from the Euroasian continent to the Arctic ocean. The experimental data on five flights of the satellite have been thoroughly investigated. It has been detected, that each type of the lithosphere structure is characterized by a special character of the low-frequency electromagnetic emission.

Strong earthquakes and their influence on the polar lower ionosphere

In the work the authors have investigated how the variations of the F2-layer electron density and temperature numerically calculated for the period of April 15-20, 2002 including two geomagnetic storms depend on the Рћ+ + N2 reaction rate taking into account the vibrationally excited molecular nitrogen. The results of numerical calculations performed using the Upper Atmosphere Model have been compared with the observation data obtained by the incoherent scatter radars. The conclusion has been made that ignoring the vibrationally excited molecular nitrogen by the numerical calculations worsens the agreement of model versions both with the observation data and with each other.
